本文的目的是探讨与人口进入公共交通系统相关的流动性机会的空间分布，以及与地区的社会经济变量和估计的当地公共交通需求相关的交通劣势限制。它的重点是哥伦比亚人口第三多的城市地区，圣地亚哥德卡利的大都市区。该分析使用并关联了两个空间化指标。社会交通需求指数和公共交通供应指数均按绝对和相对计算。对其进行了统计分析，并根据标准差进行了空间分布分析。这两个指数在绝对和相对方面进行了对比，并在空间上进行了研究，在地图上显示了每个区域的供需平衡。最后，计算Pearson和Spearman等相关系数以及显著性水平，以验证结果。结果表明：相对于其他两个指标，交通社会绝对需求指标和公共交通相对供给指标的分布呈现正态分布；在标准差图中，在研究区域外围的公共交通提供相对指数中，低于平均值的分布占多数。另一方面，中部地区交通社会需求的绝对指数和相对指数的空间分布低于或处于研究区的平均水平。可以得出结论，使用公共交通系统的机会相对较少集中在社会经济水平较低的弱势地区。
The objective of this paper is to explore the spatial distribution of the mobility opportunities linked to the access of the population to the public transport system and its transport disadvantages constraints in relation to socio-economic variables of the districts and estimated local public transport needs. It focuses on the third most populated urban area in Colombia, the metropolitan area of Santiago de Cali. The analysis uses and correlates two spatialized indexes. The index of social transport needs and the index of public transport provision are calculated, both in absolute and relative terms. A statistical analysis has been made, and a spatial analysis of distribution in term of standard deviation. Both indexes were contrasted in absolute and relative terms, and they were spatially studied in a cartography that showed the balance between supply and need in each zone. Lastly, correlation coefficients such as Pearson and Spearman were calculated along with levels of significance to validate the results. The results revealed that distribution of the indexes, the absolute transport social needs and the relative public transport provision, presents a normal distribution, in contrast to the other two indicators. Regarding the standard deviation maps, the distribution of the values below the average is shown to be the majority in the case of the relative index of public transport provision on the periphery of the study area. On the other hand, the spatial distribution of the absolute and relative index of transport social needs in the central areas is below or at the average of the study area. It can be concluded that the opportunities for access to the public transport system are relatively less concentrated in disadvantaged districts with low socio-economic levels.
